Can i use an asthavent pump during pregnancy? 33 weeks pregnant

You should if needed: I am surprised that you are asking here rather than your doctor at 33 weeks. I presume you have asthma is why you need to use Asthavent pump and looks like mild. You should be able to use your inhaler if you need to when pregnant but it is important to avoid things that could precipitate asthma attack for you. If there is no fast relief please see your medical provider for better management.
